Question

How do you translate word phrases to algebraic expressions: four times a number decreased one is -29?

Answer 1

Se the entire translation process below:

Explanation:

First, let's call "a number": `n`

Then, for "four times a number" we can write:

`4 xx n` or `4 * n` or `4n`

This expression "decreased by one" means to subtract one so we can write:

`4n - 1`

Now, this expression "is -29" means it equals -29 so we can write:

`4n - 1 = -29`
